ON Cloudmonster Trainers - Grey - UK 6.5

Yes, the ON Cloudmonster Trainers are excellent for marathon running due to their advanced cushioning and energy return, which help reduce fatigue over long distances.

These shoes are primarily designed for road running. While they offer decent grip on packed dirt, they are not ideal for technical trails due to their outsole design and lack of aggressive lug patterns.

Refer to the sizing chart provided by ON Running, which typically maps UK sizes to foot length in centimeters or inches. The product description for the Grey - UK 6.5 variant indicates this specific size.

The Cloudmonster features a more substantial amount of Helion™ superfoam and a pronounced CloudTec® configuration, offering maximum cushioning and a unique 'monster' feel for enhanced impact protection and a powerful ride, compared to lighter, more minimalist ON models.

Clean with a damp cloth and mild soap. Avoid machine washing. Allow them to air dry completely away from direct heat.

Information regarding the specific warranty period is typically found on the retailer's website or the official ON Running website at the time of purchase.

The uppers are designed with specially engineered mesh for improved airflow and breathability, keeping your feet cool during your runs.

This can sometimes occur due to moisture trapped between shoe layers. Ensure shoes are completely dry. If persistent, try sprinkling a small amount of baby powder inside the shoe.

The cushioning is designed for long-term performance, but if you notice a significant decrease, ensure the shoes are clean and that there are no obstructions in the CloudTec® elements. Prolonged heavy use can naturally reduce the initial responsiveness.

While designed for good grip, exceptionally wet or slick surfaces can challenge any outsole. Ensure the outsole is clean from debris. For very wet conditions, exercise caution and consider alternative footwear if extreme grip is paramount.
